Abstract
The effects of 1-[(E)-2-(2-methyl-4-nitrophenyl)diaz-1-enyl] pyrrolidine-2-carboxylic acid (LY29) and diphenyliodonium chloride (DIC) on the degradation of protein to ammonia were determined in a mixed rumen microbial population taken from sheep on a grass hay-concentrate diet. Both compounds decreased NH3 production by inhibiting deamination of amino acids. LY29, but not DIC, inhibited growth of the high activity ammonia-producing species, Clostridium aminophilum and Clostridium sticklandii.
